Renegotiation of Australia’s Bilateral Investment Treaties

Submission

The International Institute for Sustainable Development (IISD) urges Australia's Department of Foreign Affairs and Trade to prioritize the termination of old-generation treaties that lack modern safeguards and to pursue a new generation of treaties focused on current policy problems, cooperation, shared prosperity, and transparency.

Recommendations

  • Treaties can serve as platforms for international cooperation to address collective action problems that states cannot solve on their own. Future treaty frameworks should prioritize investments that contribute to climate mitigation, adaptation, and a just transition.

  • Treaties must go beyond merely protecting capital and instead focus on strengthening the host state’s capacity to reap long-term benefits. They should facilitate productive industrialization, local economic linkages, technology and knowledge transfers, and the creation of decent work.

  • A reimagined treaty regime should move away from providing blanket protections that override domestic regulation and instead focus on the interaction between international law and national regulation, recognizing national law as the primary regulator.

  • Transparency is a cornerstone of sustainable investment. Treaties should foster public accountability and beneficial ownership registries.

IISD welcomes this opportunity to provide input on the renegotiation of Australia’s older-generation bilateral investment treaties (BITs) with Czechia, Egypt, Hungary, Lithuania, Poland, and Romania. These treaties, concluded in the 1990s and early 2000s, are based on an outdated model that prioritizes investor protection and investor–state dispute settlement over contemporary public policy objectives. IISD recommends a fundamental shift: proactively reimagining treaties as tools for sustainable investment governance. 

Modern treaties should be proactively designed to solve today's governance challenges rather than being reactive to the failures of the past. IISD calls for a broader rethinking of the function of investment treaties that starts from the formulation of the policy problems that need addressing, rather than shoehorning solutions onto the outdated investment protection model. There are numerous problems that a modern investment treaty could help solve for Australia, its treaty partners, the planet, and its people. 

Australia has a unique opportunity to lead by transitioning away from the outdated BIT model toward a regime that actively facilitates sustainable development. We urge the Department of Foreign Affairs and Trade to prioritize the termination of old-generation treaties that lack modern safeguards and to pursue a new generation of treaties focused on cooperation, facilitation, impact regulation, and shared prosperity.

A Sustainable Asset Valuation of a Road Infrastructure Project in Queensland, Australia

This report describes how road authorities can expand traditional cost-benefit analysis for road betterment projects. A customized Sustainable Asset Valuation tool was developed for the Queensland Road Authority to expand traditional cost-benefit analysis by including direct and indirect economic, environmental, and social outcomes of road betterment projects. The report describes how this tool can be used to assess past and future investments in road infrastructure.

April 18, 2023

The customized Sustainable Asset Valuation (SAVi) tool for the Queensland Road Authority considers a wide range of benefits, using 15 indicators that include road disruption, access to services, market access, and pollution. The Excel-based tool supports the development of an economic analysis and an estimation of the internal rate of return (IRR), net present value (NPV) and benefit-to-cost ratio (BCR) that consider the economic valuation of several social, economic and environmental non-road benefits. We find that the indirect induced social and environmental outcomes of road resilience investments provide significant economic contributions that should be taken into account in the economic and financial analysis of road infrastructure investments. The report describes how this can be done.

Global Report

Uncovering the gender-disaggregated employment profile for large-scale mining, focusing on women and their occupations in 12 countries.

April 10, 2023

Rapid technological advances, increasing calls for sustainability, and the low-carbon energy transition are transforming large-scale mining across the globe. But the lack of high-quality, gender-disaggregated employment data leaves decision-makers ill-equipped to effectively support a more equal and inclusive mining workforce.

To help remedy the situation, the Women and the Mine of the Future Global Report looks at a sample of 12 countries to uncover the gender-disaggregated employment profile for large-scale mining, focusing on women and their occupations in the sector.

The report begins with a cross-country analysis that compares the data against commonly held assumptions and key trends in the sector. Next, the researchers consider what the unfolding transformations will mean for mining occupations. The report goes on to identify the main data gaps and challenges hindering evidence-based policy-making and opportunities for women to fully participate in the future of mining. The report concludes with policy recommendations for governments, companies, and workers to consider.

This global report is the final outcome of the first phase of the Women and the Mine of the Future project. It is a collaborative project led by the Intergovernmental Forum on Mining, Minerals, Metals and Sustainable Development (IGF) which has been hosted by IISD since 2015. Project partners are comprised of International Women in Mining, International Labour Organization, German Agency for International Cooperation, and the Environmental Governance Programme run by the Swedish Environmental Protection Agency and United Nations Development Programme.

Project bans correct

The Greens are right to argue for no new coal and gas projects. The International Energy Agency (IEA) works with countries around the world to shape energy policies for a “secure and sustainable future” – something we all want. The agency’s 2021 Flagship report Net Zero by 2050: A Roadmap for the Global Energy Sector clearly stated that “Beyond projects already committed as of 2021, there are no new oil and gas fields approved for development in our [net-zero 2050] pathway, and no new coal mines or mine extensions are required.” This was confirmed in its World Energy Outlook 2022 report.

As long as Australia fails to transition away from fossil fuels, its climate policy is meaningless

The Chubb review talks optimistically about ‘carbon credits’, but we wouldn’t need so many if we weren’t building so many new sources of pollution.

Doubling Back and Doubling Down: G20 scorecard on fossil fuel funding

This G20 scorecard report aims to track each of the G20 countries' progress in ending government support to fossil fuels. It has been prepared in order to increase transparency and accountability, as well as to highlight areas where more progress is needed so that G20 countries can meet their phase-out commitments and help accelerate the energy transition needed to meet our climate targets. It does so by reviewing progress in ending G20 funding to fossil fuel production and consumption between 2014 and 2019 and is complemented by an analysis of public money commitments for fossil fuel-intensive sectors in response to the COVID-19 crisis up to August 12, 2020.

November 9, 2020
  • G20 governments provided $584 billion annually (2017–2019 average) via direct budgetary transfers and tax expenditures, price support, public finance, and state-owned enterprise investment for the production and consumption of fossil fuels at home and abroad.

  • Governments provided more support to oil and gas production than any other stage of fossil fuel-related activity, at $277 billion (47% of the total support to fossil fuels).

  • Despite repeated pledges to end inefficient fossil fuel subsidies, G20 governments' support to fossil fuels has dropped by only 9% since 2014–2016: Progress made between 2014 and 2019 was insufficient and more needs to be done.

Despite various commitments since 2009 to end government support for fossil fuels and make “finance flows consistent with a pathway toward low greenhouse gas emissions and climate-resilient development” (Paris Agreement, Article 2.1c), G20 governments continued to provide significant support to fossil fuels in 2017–2019. G20 governments provided $584 billion annually (2017–2019 average) via direct budgetary transfers and tax expenditures, price support, public finance, and state-owned enterprise investment for the production and consumption of fossil fuels at home and abroad.
